[QUOTE="78f100, post: 1008737, member: 3542"] I'm not sure if I posted this in here yet or not and don't feel like looking back to see. I am certainly not as familiar with these as Morgan and Tadd but have done lots of studs without ever having a issue. I cracked my block with elite/a1 studs at 180 or 190 ftibs I can't remember exactly what they go to now. I did it by the book and it still cracked. I was able to fix it with some paste and cooling system sealer so far. You can bet from now on I will follow how Morgan does it in hopes it never happens again. I understand uneven clamping force is applied somewhat but don't think it is drastic enough to cause issue. I used a good tq wrench (mac)cleaned all the holes, used lots of lube, and went exactly by directions. I can't say for anyone else but for me it was not instillation error, and I doubt it was on most of the rest who had this happen. My old block has had 2 torques using the same studs, same process on it without issue. I think some of it is the actual casting and you never really know if it will happen or not till it's too late. So it's best to use caution and assume it will. [/QUOTE]
